Grid Grouping event for getting custom group summary

[Sandeep Gaur]

Hello,
Lets say I have Columns - C1,C2,C3, Val1,Val2,Val3,Val4
 
I have applied groups on the columns C1,C2,C3

I need a event or a way which allows to do me a lookup based on the values of C1,C2,C3 to get the summary rows (Lookup procedure will be handled by me, or I can provide another table if lookup is inbuilt)

Hi Sandeep,

Thank you for using Syncfusion Products.

I am afraid that I am unclear with your query, based on what I understood,I have suggest you following grouping related events,

    QueryAllowGroupByColumn

    GroupedColumns.Changed

    GroupedColumns.Changing

    GroupExpanding

    GroupedColumns.Changing

    GroupedColumns.Changed

    GroupExpanded

    GroupCollapsing

    GroupCollapsed

    SortingItemsInGroup

    SortedItemsInGroup

    GroupAdded

    GroupRemoving

    GroupSummaryInvalidated

please make use of any of the above events. The simplest way to do look up and get summary rows , you can make use of the Expression Fields.
